ELECTRICAL ADVERTISING DEVICE.

This invention relates to advertising apparatus.

The object of this invention is to provide a simple, attractive, easily operated, efiicient advertising novelty, and particularly to provide such a novelty including a sign structure adapted to be illuminated at successive intervals by vari-colored lights; the circuit through the lights being controlled by a moving part of the decorated sign structure.

Bin important object is to provide means for controlling the illui ination, which means will utilize as small amount oi power 6: .vention consists of the parts and *uction and combination of parts, after more fully described and wing reference to the accompany drawing, in which Figure 1 is a side elevation of a decorated sign, l aving a movable, v. ible part contrclhug the liehting effect. 2 is pers ective view of the switch. Fig. 3 is tran verse section through the switch structure.

Fig. l is *p ire view of brush. F Q a int/silica ion showing batter circuit.

It is a desideratuni to provide my device in combination with certain advertising signs, having a movable decoratedpart, such, for instance, as is shown in Fig. l, in which is represented a barbers pole 2 having a decorated cylinder 3 rotatably mounted upon the pole, which is secured upon a shaft 4, to which power may be applied from any suitable source, not here shown. This style of advertising structure is rendered attractive by account of its coloring and the tie decorated or striped cylinder 3, but night, should the pole be erected at any distance from a good light, the pole structure becomes almost or entirely invisibio, and in order to render the device more effective to serve its purpose, it is our inten- 4 Specification of Letters Patent.

tion to erect in combination with the moving member a system of lights controlled by the movement of the member, whereby the rays of lights, themselves beinginvisible, will be cast upon the moving cylinder 3 and rcn der the same visible.

In practising our intention we attach at the upper end of the cylinder shaft 4 asuitable, transparent. non-electric conducting disk or switch plate 5, which is disposed horizontally in a cap 6 of the sign. The upper portion of the cap 611215 a globe 7, which may be transparent or opaque, as desired, and in this is erected a cluster of vari-colored lights 8, which, for instance, may be red. white and blue in harmony of coloring, with the sign. The sockets ot the several lights are connected, as shown in Fig. 2, to a main electric conductor 10 by branch wires ihand the sockets attached by brush wires 12 to respective brushes 13. The brushes adapted to rest upon an annulus or flat ring ll oi conducting material, which is electrically energized by a main brush 15, to which is connected the return main re l6. Thus, current enters the ring it which is secured upon. the upper surface of the turnable switch 5 and flows through the sev eral brushes to the lights, thence out on the main lead 10. Preferably the brush l5 bears on the outermost portion of the corn ductor ll, while the several light brushes 13 bear upon c 'e thereof nearer the center oi the 5, and for the purpose of intern curly flashing and cutting oil. the illuuiin: ion by the lamps 7, there may be pro, ed a plurality of insulating segments, as i? and 18, the former of which is comparatively long, so that all of the brushes 13 may simultaneously rest thereon and thus break the circuit 01 the several lights at one time. During the rotation of the disk switch 5, the insulator segment 17 nio ii the brushes, these being lifted from contact ring ll, thus breaking the lamp circuit. is the segmental insulator 1'? passes from beneath each brush, the brush will be permitted again to contact with the ring thus closing its respective lamp circuit, each lamp being energized successively, as brush pas s 0 i" the end of the conductor segment 1?. By placing a plurality of the short segments 18 at any desired disparent, non-conducting material, danger of leaking of the current to the other portion of the apparatus is avoided, and a minimum obstructlon of the rays of light passing downward through the'cap 6 is obtained.

The rays, continuing through the transparent disk 5, reach the cylinder 3, which may be made of suitable material, transparent, if desired; thus, the latter will be illuminated at desired periods with various colors or with a mixture of the several colors when all of the lights are illuminated simultaneously.

Inasmuch as it is desired to conserve power to the greatest possible extent, we have shown in Fig. 4 a very eficient and yet easy running form of brush, in which there is 'provided a ball 19, which rests between the up wardly folded leaf 20 of the brush 13, which presses the ball 19 so as to rest upon a seat 21, preferably of less diameter than the ball 19, so that when the brush 13 is en-' tirely lifted from the support upon which the ball 19 travels, the pressure of the spring fold or leaf 20 will not push the ball through the seat 21. When the brushes are assembled in place, the balls 19 rest upon the upper surface of the contact ring 14 and constantly bear on the lower surface of the spring or fold 20, thus at all times making a positive contact. By this form'of rolling antifrictiondevice, the brushes, while mak-. ing good contact, will not bear with sufficient pressure to materially retard the movement or rotation of the revolving disk switch 5. v

If the brushes are in the main circuit, it is necessary that they bear su'ficiently to insure a perfect contact, thus effecting a material resistance to the moving part, therefore, in Fig. 5, the switch brushes are shown as connected in a battery circuit 22, of which there is v a branch for each brush, each branch including a magnet 23, which, when energized, will attract its armature 24, thus in turn closing a circuit through its wire 12 to a lamp in the main circuit. By

, this latter arrangement a very delicate brush structure and weak current will be sufiicient to control the lamps.-

Having thus described our invention, what we claim and desire to secure by Letters Patent isv 1. The combination of a transparent, rev oluble non-electric table, an annulus mounted upon the upper surface of said table, an electric conductor constantly contacting with said annulus andenergizing the same, a plurality of non-conducting-segmeuts arranged on the annulus, and a series of lamp circuit controlling brushes adapted to contact the annulus and be insulated therefrom during the movement of the table by said segments. r

2. lhe combination of a series of multicolored lights, a rotatable transparent switch table, an annulus mounted upon the upper surface of said table, an electric conductor constantly contacting with said annulus and energizing the same, a series of brushes connected in the lamp circuits hearing upon said annulus, a plurality of insulating segments of various lengths arranged on the annulus and adapted to interrupt the lamp circuits by breaking the contact of said brushes with the annulus.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
